Ok i recently bought a 01 chevy blazer. and I was installing some small 10's into the blazer and the car died. When we jumped the car we noticed once we tried to move the car it turn on and changed gears into R but the car would not go any where. It only rev's. We unhooked everything we added for the speakers. We didnt cut any wires, nothings not correctly hooked up...no fuses blown. The only thing i did that ive never done was have the E brake on. I was thinkin maybe i fired the safty sensor???? other then that im stumped. Does anyone have any ideas that i can try... Please and thank you/.
